Beckett's never taken being the center of attention very well, so when Kate changes direction on her, enough of her is aware to cause the sort of self-conscious laugh that spills from her lips.

Beckett sighs, instead, suddenly feeling heated all over, desire pooling low in her belly, and soon it's too hard for her to keep herself propped up, so she doesn't even bother, laying back on the bed with the two of them leaning over her.
